front-end/alignment settings

Standard/original-style front-end parts?
What PSI in the tires?
What tire size on those wheels?

If all else fails (or, the alignment shop says all the alignment settings are good) decrease the PSI by 1 psi and go for a run/ride to test the steering. Too high pressure often causes wandering.

Continue by 1PSI decreases until the steering gets good or until it gets tough to steer.
If it gets tough before it gets good, the problem is not tire pressure.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
